In April 2012, the month their debut album was released, the Lumineers played to a packed crowd at the tiny 7th Street Entry. By summer, the Denver ensemble was performing "Ho Hey" and their sing-along anthems at the Basilica Block Party. But are Wesley Schultz and his charming coed group ready for an arena? After all, this is basically acoustic music with a cello. Maybe those choruses of "Oh-ee-oohs" and "ho heys" will fill a basketball arena more effectively than the injury-riddled Timberwolves did. Opening are Cold War Kids, the indie rock favorites who added ex-Modest Mouse guitarist Dann Gallucci for their just-released fourth album, "Dear Miss Lonely Hearts," and rowdy Southern rockers J Roddy Walston and the Business. (7:3 p.m. Fri. Target Center, $30-$45.) Jon Bream

Another one-man act with a pseudonym that's now a band, Night Beds is getting airplay on 89.3 the Current with its wistful lament "Ramona." The single offers just a hint of the compelling drama and vocal power of the full album, "Country Sleep," on which Nashville-based mastermind Winston Yellin sounds like Rufus Wainwright or Jeff Buckley playing in an Americana band. Like fellow pseudonym user Bon Iver, he crafted the songs while holed up alone in a cabin, one that used to belong to Johnny Cash. Must be something in the water. Fellow indie-twang buzz act the Staves, a trio of sisters from England, open with Musikanto. (8 p.m. Fri., Varsity Theater, $12-$15.) Chris Riemenschneider
As if there already weren't enough odd dimensions to Primus, the warped '90s space-funkers have embarked on a groundbreaking 3-D tour. Fans will be given glasses upon arrival along with warnings of possible motion sickness from the hi-fi production, inspired by their hometown San Francisco visual pioneers at Lucasfilm. Presumably, attendees already know to also beware of bass solos. Les Claypool and the guys have been playing two sets on tour with songs from all eras. (8 p.m. Sat., Myth, $36.50.) Riemenschneider
Two titans of Twin Cities music — Doomtree and Morris Day & the Time — collide in one big outdoor Summer Party to raise money for the Minneapolis Institute of Arts. With Dessa on the road this summer, this is the last chance to catch Doomtree until August. And while this edition of the Time doesn't boast the "Original Seven" (who split again last year), Day and cohorts Monte Moir and Jellybean Johnson still bring the "Jungle Love." (8:30 p.m. Sat., MIA's Target Park, 2400 3rd Av. S., Mpls. $85 includes a free drink and finger food. tickets.artsmia.org) Tim Campbell
Perhaps better known now for their kids albums and TV themes ("The Daily Show," "Malcolm in the Middle"), They Might Be Giants are once again making "adult" records, loaded with the catchy, eclectic, semi-kitschy nerd-folk and gyspy-rock that once made them dorm-room favorites. Their latest, "Nanobots," was even produced by the same guy as their hit 1990 album "Flood" and is loaded with 25 songs total. Moon Hooch opens. (9 p.m. Sat., First Avenue, $23.) Riemenschneider
Grand Old Day is back, the only block party to extend for a full mile and be half-full of cover bands. The Dixie's on Grand Stage welcomes back Har Mar Superstar (4 p.m.), who channels classic soul with impressive aplomb on his new album "Bye Bye 17," plus road-tested psychedelic pop-twangers Night Moves and hip new Springsteen tribute act Tramps Like Us. The Wild Onion Stage is all country, including White Iron Band (noon) and Tim Sigler (2:30). KQRS' Pier 1 Stage welcomes dance-rockers Apollo Cobra (noon) and E.L.nO. (3:30). Other cover groups include '70s throwbacks Hookers & Blow (3:30, Billy's Stage) and the always fab Rubber Soul (1:30, Twin Cities Live Stage). (8 a.m.-6 p.m. Sun., Grand Avenue between Fairview and Dale, St. Paul, $8 and 21 & older for performance/beer areas.) Riemenschneider
Son Volt has gone country — straight-up, violin-laced, sawdust-floored country, befitting the title of its latest album, "Honky-Tonk." This should be no shock to fans of frontman Jay Farrar's old band, Uncle Tupelo, and it's an interesting side trip for his modern Son Volt lineup, which seems to be having fun here. They're playing plenty of the rocking favorites on tour, too. Opening band Colonel Ford is a weekend sort of trad-twang act featuring Farrar's brother Dade and other St. Louis-based cohorts. (8 p.m. Tue., First Avenue, $20.) Riemenschneider
Australian duo Atlas Genius has been steadily on the rise with its dream-pop single "Trojans," which — as the chorus suggests — gets easily stuck in your head. The rest of the band's Warner Bros. debut, "When It Was Now," sounds like a blend of Phoenix's whirring dance-rock and Duran Duran's slick pop. New York openers the Postelles just dropped their sophomore album last month, "And It Shook Me," a poppier set than their Strokes-echoing debut. Haerts also perform. (9 p.m. Tue., Fine Line, $12.)
